First, relax. Few people know what they want to do, really. James Michener allowed as how anything you do before you are 40 is just training.

If you are thoughtful, you will figure it all out. Don’t rush it. Have some experiences, variety to your life. Along the way, someone or something will trigger some passion in your life. It happened for me when I was about 32 or so—and it happened out of sheer luck and timing.

What is important is to be ready for these moments. Get experience. Be open to new things. Try something. Learn. Ask for more responsibilities. Find someone older you admire, and ask him/her out for coffee. Don’t ask “what should i do?” Instead just listen, tell your own stories, listen to theirs. Above all, listen.
